Detailed ways

The following will describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

The core of this application is to provide a hinge structure for smart glasses, which is convenient for assembly.

The first specific embodiment of the smart glasses hinge structure (hinge structure for short) provided by this application, please refer to Figure 1 to Figure 28, includes several hinge frames 2 arranged in sequence along the preset direction, and the adjacent hinge frames 2 pass through the hinge shaft 6 hinged.

In this embodiment, four hinge frames 2 are provided, and in other embodiments, other numbers of hinge frames 2 may also be provided.

Wherein, since the hinged frames 2 are hinged, the hinged frames 2 may not always maintain a straight line state, and accordingly, the preset direction may be a straight line or a curved line.

A reset assembly 5 is arranged on the hinge shaft 6 . When the hinge frame 2 at one end swings to a set angle relative to the hinge frame 2 at the other end toward the preset valgus direction, the reset assembly 5 provides a reset force to the hinge frame 2, so that the corresponding hinge frame 2 has Tendency of movement against the preset direction of eversion.

Among them, for the preset valgus direction, the hinge frame 2 at one end of the hinge structure is the fixed end, the hinge frame 2 at the other end is the movable end, and the movable end is bent inwardly by the limit of bending relative to the fixed end. The movement direction that changes from the state (as shown in FIG. 15 ) to the unfolded extreme eversion state (as shown in FIG. 21 ) is the preset eversion direction.

Wherein, when the hinge structure is everted along the preset everted direction, the reset components 5 may start to deform at the same time, or not all of them start to deform at the same time. The set angle can be specifically defined as the critical value at which all reset components 5 start to deform. After the hinge structure is turned outward to the set angle and continues to be turned outward, each reset component 5 is in a deformed state. In this embodiment, the preset angle is the limit inward-folding state, that is, as long as it is everted, the reset component 5 will provide corresponding inward-folding reset force.

A damping elastic member 7 is arranged on the hinge shaft 6, and the damping elastic member 7 squeezes at least one hinge frame 2 to provide a damping force when the corresponding hinge frame 2 swings.

When applied to smart glasses such as AR glasses, the hinge frame 2 at the two ends of the hinge structure connects the mirror frame 1 and the mirror leg 3 respectively, so that the mirror leg 3 is rotatably connected to the mirror frame 1 through the hinge structure, and the mirror leg 3 can be relatively The picture frame 1 is folded inward or outward. During the wearing process, the user swings the temple 3 along the preset valgus direction, and each hinge frame 2 also moves correspondingly along the preset valgus direction, and the degree of deformation of the reset component 5 gradually increases, so that the temple 3 keeps moving along the preset direction. The trend of reset movement in the inward folding direction, the preset inward folding direction is opposite to the preset valgus direction, so that the two temples 3 can be pressed against the head respectively, and the two temples 3 clamp the head. The smart glasses can be adapted Wearing with different head shapes increases the applicability and comfort of wearing; at the same time, when the temples 3 are everted, the damping elastic member 7 generates a frictional force on the corresponding hinge frame 2 as a damping force to improve the use feeling.

In this embodiment, the reset assembly 5 and the damping elastic member 7 are uniformly arranged on the hinge shaft 6, and the reset assembly 5 and the damping elastic member 7 can be positioned directly on the hinge shaft 6, which can be installed uniformly to facilitate the assembly of the hinge structure.

Further, the pressing force of the damping elastic member 7 against the corresponding hinge frame 2 is adjustable. Since the pressing force is adjustable, the damping force received by the hinge frame 2 is adjustable, which can adapt and improve the use feeling according to needs.

Further, referring to FIG. 4 , and FIG. 10 to FIG. 12 , at least one pair of adjacent hinge frames 2 are respectively fixed with mounting plates 21 to form a plate group. Wherein, the hinge shaft 6 is plugged into each mounting plate 21 in the axial direction, and the damping elastic member 7 compresses at least two adjacent mounting plates 21 connected to the two hinge frames 2 respectively, and the compressed mounting plates 21 Friction is generated during relative rotation to provide damping force. The damping force is provided through the friction between the mounting plates 21 to ensure the damping effect. Of course, in other embodiments, the relative rotation between the damping elastic member 7 and the mounting plate 21 that it contacts can also provide frictional force as the damping force.

Further, as shown in FIG. 10 and FIG. 11 , an end cap 62 is provided at one axial end of the hinge shaft 6 , and the damping elastic member 7 is axially positioned between one end of the plate set and the end cap 62 . The axial distance between the end cap 62 and the plate pack is adjustable. The pressing force of the damping elastic member 7 on the hinge frame 2 is adjusted by adjusting the axial distance between the end cap 62 and the plate group, and the operation is convenient.

Further, as shown in FIG. 11 , the other axial end of the hinge shaft 6 is a threaded rod, on which a locking nut 63 is threaded, and the plate group is sandwiched between the locking nut 63 and the end cap 62 . Wherein, specifically, the damping elastic member 7 is a disc spring sleeved on the hinge shaft 6, and may also be other springs. In addition, as shown in FIG. 10 , the elastic damping member 7 , the plate member and the end cap 62 may be separated by spacers 61 sleeved on the hinge shaft 6 .

In this embodiment, the hinge shaft 6 is installed axially on the elastic component, the damping elastic member 7 and the mounting plate 21 sequentially, and then the locking nut 63 is connected to complete the assembly of the hinge shaft 6 components, which is easy to operate. In addition, by turning the locking nut 63 and adjusting the axial distance between the locking nut 63 and the end cap 62 , the degree of extrusion to the damping elastic member 7 can be adjusted to adjust the damping force. Of course, in other embodiments, it is also possible to directly set threads in the plate hole of one of the mounting plates 21 to form a threaded plate hole, and the threaded rod on the hinge shaft 6 is directly threaded to the threaded plate hole, and the axial connection between the two can be adjusted. position, the damping force of the damping elastic member 7 can be adjusted.

Further, as shown in Figure 11, between at least one pair of adjacent hinge frames 2, each mounting plate 21 in the plate group is divided into two sub-plate groups 25, and is arranged on both ends of the hinge frame 2 in the axial direction, reset The assembly 5 is arranged between two sub-board groups 25 .

By arranging the two sub-board groups 25 at the two ends of the hinge frame respectively, it is possible to ensure that there is enough space to install the reset assembly 5 between the two sub-board groups 25, and at the same time, fill the reset assembly 5 in this space, which can Improve the overall connection strength of the hinge structure.

Further, as shown in Figure 11 and Figure 12, in at least one pair of adjacent hinge frames 2, one of the hinge frames 2 is fixedly connected to the hinge shaft 6, and the reset assembly 5 includes a fixed block 51 fixed on the other hinge frame 2 , the movable block 52 axially slidably connected to the hinge shaft 6 and the return elastic member 53 axially compressing the movable block 52 on the fixed block 51 . When the hinge frame 2 at one end swings to a set angle relative to the hinge frame 2 at the other end toward the preset valgus direction, the movable block 52 cooperates with the slope between the fixed blocks 51 to make the corresponding hinge frame 2 has a movement tendency opposite to the preset valgus direction.

Specifically, as shown in FIG. 19 , the fixed block 51 is provided with a fixed inclined surface 512 inclined relative to the axial direction, and the movable block 52 is provided with a movable inclined surface 522 inclined relative to the axial direction, and the two keep fit together. When the movable block 52 rotates with the hinge shaft 6, the fixed block 51 is relatively stationary. Under the promotion of the fixed slope 512, the movable block 52 moves axially away from the fixed block 51 and compresses the reset elastic member 53, and the elastic force of the reset elastic member 53 is restored. The inward-folding reset force generated by the hinge frame corresponding to the turning ability of the movable slope 522 and the fixed slope 512 .

Wherein, in order to realize the axial movement of the movable block 52 without keeping the circumferential position unchanged with the fixed block 51 , specifically, the movable block 52 is axially slidably connected to the hinge shaft 6 through a key structure. Alternatively, the two ends of the reset elastic member 53 are fixedly connected to the movable block 52 and the mounting plate 21 respectively, and the torsional reset force of the reset elastic member 53 is used to prevent the movable block 52 from rotating excessively and can rotate with the hinge shaft 6 .

Wherein, as shown in Figures 9 and 10, the fixed block 51 is rotatably sleeved on the hinge shaft 6, and at the same time, on the hinge shaft 6, the fixed block 51, the movable block 52 and the reset elastic member 53 are sequentially sleeved in the axial direction. set up.

Through the fit of the inclined surface, the axial pressure of the reset elastic member 53 received by the movable block 52 can be converted into a pressure perpendicular to the axial direction, so as to produce a reset force perpendicular to the axial direction on the hinge frame 2 that is undergoing eversion movement, so that The hinge frame 2 that performs the eversion movement has a movement tendency of inward folding and reset, which can fully allocate the axial space at the hinge shaft 6 to complete the assembly of the fixed block 51, the movable block 52, the reset elastic member 53 and the damping elastic member 7, which is further convenient assembly.

Further, the fixed block 51 includes a fixed plane 511 perpendicular to the axial direction, and the movable block 52 includes a movable plane 521 perpendicular to the axial direction. In the extreme inward folding state, the fixed plane 511 and the movable plane 521 abut against each other along the axial direction.

Wherein, as shown in Fig. 3 to Fig. 8, positioning rib 514 is fixedly arranged on the fixed block 51, and positioning groove 22 is set on the hinge frame 2, and positioning rib 514 is positioned and inserted in the positioning groove 22 and welded, so that the fixed block 51 and The hinge frame 2 is formed as a whole, and the fixing block 51 and the hinge frame 2 are welded to each other, so the manufacture is simple. In addition, the fixed block 51 and the hinge frame 2 are formed by sheet metal stamping or simple machining, which can reduce costs.

Wherein, as shown in FIG. 4 and FIG. 9 , the fixed plane 511 on the fixed block 51 and the fixed inclined surface 512 are butted along the circumferential direction, and the movable plane 521 and the movable inclined surface 522 on the movable block 52 are butted along the circumferential direction. Specifically, in the extreme inward-folding state as shown in FIG. 15 , the fixed plane 511 and the movable plane 521 contact and abut in the axial direction; as the movable end of the hinge structure swings relative to the fixed end along the preset outward-turning direction , the movable block 52 rotates while the position of the fixed block 51 remains unchanged, and the movable inclined surface 522 slides against the fixed inclined surface 512, so that when the movable block 52 rotates with the hinge shaft 6, the movable inclined surface 522 drives the movable block 52 to move axially, compressing and resetting the elastic member As the degree of 53 increases, the driving force for driving the corresponding hinge frame 2 to fold back and reset also increases. In addition, the axial distance between the movable plane 521 and the fixed plane 511 also increases.

In addition, as shown in Figure 16, the fixed block 51 is also provided with a fixed inner limiting surface 513 parallel to the axial direction, and the movable block 52 is provided with a movable inner limiting surface 523 parallel to the axial direction. The fixed inner limiting surface 513 and the movable inner limiting surface 523 are matched against each other along the circumferential direction, so that the corresponding hinge frame 2 cannot continue to rotate inward, and the inward folding is performed to limit the position. In addition, as shown in Figure 9, the hinge frame 2 is provided with an outer limit surface 211. In the extreme eversion state, the outer limit surface 211 between adjacent hinge frames 2 abuts to prevent the corresponding hinge frame 2 from continuing to eversion.

In this embodiment, due to the abutment between the fixed plane 511 and the movable plane 521 , the stability of the installation between the movable block 52 and the fixed block 51 can be improved when the smart glasses are not used and the hinge structure is in an extreme inward folding state.

Further, as shown in Fig. 23 and Fig. 24, the smart glasses hinge structure also includes a ring-shaped hinge cover 4, and a hinge cover 4 is sleeved and fixed on the outside of each hinge frame 2, and each hinge cover 4 is connected along a preset direction to form an installation channel. 46. The protection of the hinge frame 2 can be achieved through the sleeve of the hinge on the outside of the corresponding hinge frame 2 . Specifically, each hinge shaft 6 is fixed on a different hinge cover 4 . The hinge frame 2 and the hinge shaft 6 are respectively fixed on the hinge cover 4 to realize the fixed connection between the hinge shaft 6 and the hinge frame 2, and there is no need to set a separate fixing structure on the hinge shaft 6 to fix the hinge shaft 6. After assembling the hinge frame 2 At the same time as the hinge cover 4, the hinge shaft 6 is fixed, which further facilitates the assembly of the hinge shaft 6.

Further, as shown in FIG. 12 , the hinge frame 2 is provided with a shaft groove 492 , and the hinge shaft 6 is inserted into the shaft groove 492 and has an interference fit for fixed connection, which facilitates the fixed connection between the hinge shaft 6 and the corresponding hinge frame. Certainly, in other embodiments, the hinge shaft 6 may be fixed to the corresponding hinge frame 2 by other means such as screw connection.

Wherein, when the hinge structure is applied to smart glasses, the two hinge covers 4 at the ends are end hinge covers, and the other hinge covers 4 in the middle are called middle hinge covers. The two end hinged covers are respectively integrally arranged on the shells of the mirror frame 1 and the mirror legs 3 .

Specifically, for the hinge frame 2 at the end, as shown in FIGS. 3-6 and 12 , screw holes 23 and positioning holes 24 are provided on it, and are fixedly connected to the end hinge cover through screw posts 47 and positioning posts 48 . In addition, a shaft groove 492 is provided on one of the end hinge covers for fixedly connecting the hinge shaft 6 , while the other end hinge cover is not fixedly connected to the hinge shaft 6 .

Specifically, as shown in FIG. 13 , the middle hinge cover includes a first side plate 49 and a second side plate 45 abutting with the first side plate 49 to form a ring structure. A plug-in structure 491 is provided on the side of the first side plate 49 facing the second side plate 45 , and the hinge frame 2 is plugged and fixed with the plug-in structure 491 . Specifically, in this embodiment, as shown in FIG. 11 , the insertion structure 491 is a bolt, and the connecting hole 26 is correspondingly provided on the hinge frame 2 to be inserted and fixed with the bolt. In other embodiments, the plug-in structure 491 may also be a slot, and the hinge frame 2 is correspondingly provided with plug-in posts for plug-in connection with the slot.

When assembling the hinge frame 2 and the corresponding middle hinge cover, first make the first side plate 49 and the second side plate 45 in a separated state, install the hinge frame 2 on the first side plate 49, the hinge frame 2 and the plug-in structure 491 Inserting and fixing, specifically, screw connection can be used to realize the position limitation between the hinge frame 2 and the middle hinge cover, and then, the second side plate 45 is fastened to the first side plate 49 .

The hinge frame 2 and the hinge cover in the middle can be reliably positioned in a predetermined direction through the plug-fitting of the hinge frame 2 and the plug-in structure 491 . In addition, the split first side plate 49 and the second side plate 45 are cooperatively connected to form the middle hinge cover, which is convenient for assembly with the hinge frame 2 in the middle hinge cover.

More specifically, as shown in FIG. 13 and FIG. 14 , a C-shaped shaft groove 492 is provided on the first side plate 49 , and the opening of the shaft slot 492 faces the second side plate 45 . Preferably, the first side plate 49 is a U-shaped plate, shaft grooves 492 are provided on two opposite walls of the U-shaped plate, and the second side plate 45 is installed on the side opening of the first side plate 49 . Wherein, shaft grooves 492 are provided on each hinge cover in the middle to fixedly connect one hinge shaft 6 respectively.

During the installation of the hinge frame 2 towards the inside of the first side plate 49 through the lateral opening of the first side plate 49, the hinge shaft 6 can enter and be fixed in the shaft groove 492 through the opening of the shaft groove 492 synchronously, specifically interference fit , to position the hinge shaft 6 through the shaft groove 492 to ensure that the hinge shaft 6 is not loose, so as to realize the synchronous positioning of the corresponding hinge shaft 6 and the hinge frame 2 through the middle hinge cover to ensure that the hinge frame 2 and the middle hinge cover swing synchronization.

Further, as shown in FIG. 23 , the flexible circuit board 8 and the flexible heat-conducting material 9 are arranged in the installation channel 46 . The flexible circuit board 8 and the flexible heat-conducting material 9 can be connected to relevant components, heat sources, and heat-spreading parts on the side of the mirror leg 3 and the mirror frame 1, respectively, so that the relevant hardware, heat source, and heat-spreading structure on the side of the mirror leg 3 and the mirror frame 1 can be connected to each other. Connected, so that the data of the whole machine can be connected, and the heat uniformity effect of the whole machine can be achieved. Wherein, the flexible thermally conductive material 9 may be a material with high thermal conductivity such as flexible graphite sheet and flexible graphene that can be bent multiple times.

In addition, if the hinge structure includes at least two hinge frames 2, then the same amount of rotating joints should be included accordingly. By setting multiple joints, each rotating joint can share the total swing amount of the hinge structure, which can increase the bending radius of the hinge cover 4 assembly. , so that the bending area between the hinge covers 4 has a small amount of expansion and contraction before and after bending. When the hinge structure swings, taking the swing of 90° as an example, among the four swivel joints, the right end swivel joint is fixed, and the rest of the swivel joints are all swung 30° relative to the right end adjacent swivel joints, and finally the leftmost swivel joint is relatively Swing 90° from the initial position. By increasing the bending radius, the swing reliability of the flexible circuit board 8 and the flexible heat-conducting material 9 inside the installation channel 46 can be improved, enabling mass production to be achieved.
